Unfill with anglebetween

Unfill with anglebetween

[David Arnold]

All,

I was trying to help a student today and the following came up.

drawarrow anglebetween(path1, path2, btex $\theta$ etex)

Is there some way to typeset the theta with an "unfilled" background?

David.

I know there is a metapost way to do this, but cannot recall where I read 
that. Something along the lines of (untested)

pic p; p := btex $\theta$ etex ;
unfill (boundingbox p) at the right location ;
draw p ;

However, if you are using the ConTeXt interface, there are easier ways. 
This is what I sometimes use

\definetextext[parbox]
   {\framed
     [     frame=off,
           width=2cm,
          height=.85cm,
       autowidth=no, %also try yes
           align={middle,middle},
     backgroundcolor=white]}

And then

\startMPcode
   drawarrow anglebetween (path1, path2, \sometxt[parbox]{$\theta$} ;
\stopMPcode
